Hi,
l have small question to know if it is possible to know my multirotor position (x,y,z) using arducoptor without GPS in indoor environment ?
l know that l can obtain my current attitude , but how about the position ?

The Parrot uses optical flow sensors and you can use a sonar to measure your position off the ground. Rather than knowing the exact x,y,z , indoor environments usually apply a 'relative-to-the-wall/ground' approach. In environments where you don't have prior knowledge, you can still navigate and explore the environment. In other environments you should use a map of some kind.
If you start the copter in any of the given rooms, you can still determine the position using so-called particle filters.
There's an excellent course on advanced navigation on udacity.com, where the course explains how some of the algorithms in the google car work.
You would need to know where you started.
